JR Wheels SL04

JR Wheels SL04 - Super Light Series FlowForm with Four and Five-Hole PCD Starting at 15 Inches

The Broadest PCD Programme in the SLS Range, Covering Alpine A290, BMW M2, and Toyota GR Supra from ET15 to ET51

JR Wheels SL04 is a FlowForm monoblock wheel from the Super Light Series, distinguished within the SLS catalogue by its dual 4-hole and 5-hole PCD programme and its minimum diameter of 15 inches — the lowest entry point of any SLS model. The SL04 targets builders on compact performance cars who need the widest fitment compatibility, including vintage and classic platforms on 4-hole PCDs that other SLS models cannot accommodate.

JR Wheels SL04 Design and Engineering: FlowForm with Dual 4-Hole and 5-Hole PCD Support

The SL04 is produced using the FlowForm barrel process, in which a cast blank is spun under heat and roller pressure to elongate the barrel wall, refining grain structure and improving tensile strength while reducing wall thickness and overall wheel mass. Beginning in 15-inch at approximately 5.15 kg, the SL04 is the lightest entry in the Super Light Series size programme. The five-step diameter range from 15 to 19 inches is wider than the SL05's three-step 18-to-20-inch window, and the dual 4-hole and 5-hole PCD support opens the SL04 to a substantially larger pool of vehicles. The ET15-to-ET51 offset range accommodates standard, flush, and mild wide-body setups across the full diameter programme.

JR Wheels SL04 Available Finishes

Gold is the standout option in the SL04 programme, applying a warm bright metallic tone suited to JDM-influenced compact builds and Alpine A290 or Renault-platform builds where a contrast finish reinforces the car's character. Matt Gun Metal covers the European performance norm, while Matt Bronze addresses the warm earthy tone. Matt Silver provides a neutral bright option without committing to Gold. Matt Black and Gloss Black handle stealth and standard demand, and Custom Finish opens the programme to any specification.
